Years ago, pedal bass or left handed bass wasa the only option for a single act, so some of us are used to it.
Flexibility is the key for me. Having the option of playing a pedal bass allows for dramatic, custom endings after the arranger function is turned off at the end of a tune,
Free form tune introductions, manual playing when the auto baseline isn't appropriate, etc.
It gives you more control over the over-all performance.
I use both, plus left-handed "Jimmy Smith"
type bass.
But that's me...
